Crews were dispatched at 9:16 a.m. to Stylist Hair Salon at 197 Pelton Center Way for a report of the building on fire, Alameda County Fire spokeswoman Aisha Knowles said. The fire was knocked down in about 20 minutes, Knowles said.

A firefighter went to an area hospital with non-life threatening injuries.

The fire started in a room used for facials and the cause was electrical. A damage estimate was not available Sunday evening as the fire investigator was still compiling that information, Knowles said.
